It's actually an '89, but yeah still way more complicated than something like your average 70s motor. I used to be pretty intimidated by working on cars, but I've gradually learned a lot just through routine maintenance and fixing shit myself (and helping my dad out with his MGB projects), and realized they're not as bad as I thought. Diagnosing a problem not specific to one part of the engine can be pretty hard, but once you know what needs to be done, it's just a matter of how much stuff you have to take apart and how hard it is to remove those bolts, hoses, parts, etc.
